Compare any two graphics cards:
Radeon R9 M280X vs Radeon R9 M380
IntroThe Radeon R9 M280X has clock speeds of 900 MHz on the GPU, and 1375 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.Compare all of that to the Radeon R9 M380, which has core clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R9 M380 should theoretically be a bit faster than the Radeon R9 M280X overall. (explain)
Texel RateThe Radeon R9 M280X is a lot (about 26%) faster with regards to AF than the Radeon R9 M380. (explain)
Pixel RateThe Radeon R9 M380 will be just a bit (about 11%) faster with regards to FSAA than the Radeon R9 M280X, and also will be able to handle higher screen resolutions better. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
